Raypak 014939 Digital P-R266A-EN-X #51 Pool Heater, Natural Gas, 240,000 BTU, Cupronickel

This is the Raypak Digital 266A with a cupronickel fin-tube heat exchanger in place of the standard copper one. The propane cupronickel 266A is a different item number (014951). The copper 266A (item 009217) is rated at 266,000 BTU/hr. Raypak lists other versions of this model with different burner orifices, so ask before ordering for an installation above 2,000 ft.

• Outdoor installation as shipped, using the stackless top packed with the heater. Indoor installation needs Raypak indoor stack kit 009839 and a vent to the outside, or the D-2 power vent kit (010744 for 120 V, 009832 for 240 V).

Good to know

• Replacement heat exchangers and tube bundles for this heater must be the cupronickel versions; Raypak states copper and cupronickel parts are not interchangeable.
• Raypak reduces the input 4% for each 1,000 ft above sea level beyond 2,000 ft, so order the version built for your elevation.
• The ProTek Shield is a wear item; replace it when its weight has dropped to about 40% of the original.
• Salt chlorinators and chemical feeders must be plumbed downstream of the heater. Raypak's water chemistry table allows up to 4,500 ppm salt.
• Gas, venting and electrical work must be done by a qualified installer and meet local codes. Raypak's warranty applies to heaters installed by a licensed service provider.
